Abstract
The method enables operation of a device for spatial expansion of a subscriber lead unit (DLU) of a telecommunication exchange or of a digital telecommunication terminal exchange for small number of connections. Decentralised interface units (RT) are provided for subscriber side connection of at least one subscriber terminal connection circuit (SLM) to the head system. Each command for a subscriber terminal reached by the central interface (COT) causes the central interface (COT) to control the lead unit (DLU) to reach the spatially remote terminal. The lead unit control (IOP) supplies information to the central interface (COT) on all connection circuits (SLM) of the terminal without reference to their actual position. The central interface (COT) delivers the control (IOP) of the lead unit for each connection circuit (SLM) which are not components of the lead unit (DLU). The control (CP) of the exchange transmits information deriv. for the decentralised terminals, to the central interface (COT) from which the information is relayed to the terminals.

C) central interface unit (COT) conduct is to the answer of the controller (IOP) of user line unit, notify those user's connecting circuits or user's connecting circuit group (SLM), these connecting circuits or circuit bank are not the parts of user line unit, but can get in touch through them and part as discrete interface unit (RT), so that link to each other with the line system in every kind of situation of user's connecting circuit (SLM) of user side
D) controller of telecommunications exchange (CP) sends to central interface unit (COT) to the information of preparing to discrete subscriber terminal equipment sends, from information being passed on to subscriber terminal equipment here again.
Therefore, method of the present invention is compared with technology up to the present, the control of user line unit be not by the central authorities control of telecommunications exchange but by ancillary equipment position about user's connecting circuit, circulate a notice of particularly which is long-range installation in whole operational user's connecting circuits.Therefore, the installation that is used for the equipment of extending user line unit does not require any change of control desk.Particularly do not require any change of the central control board of telecommunications exchange, and removed above-mentioned up to this point needed hardware change.
One step was set forth method of the present invention during below by embodiment in the accompanying drawing.
Accompanying drawing shows the structure of a telecommunications exchange, and this structure has a device that is used to expand the affiliated user line unit of telecommunications exchange, and what method of the present invention related generally to is this device.Show the central controller CP of a coordination processor form about telecommunications exchange, a central catenet SN, one of coupling assembling LTGB and many user line unit DLU are used to connect the connection line of subscriber's line and branch equipment.
The user line unit DLU that links together through elementary multi-path line PCM and coupling assembling LTG can be the part of exchange or install at a distance with this exchange.
The connection line of subscriber connection line and branch equipment was finished through many user's link SLM with being connected generally of user line unit DLU, and one of them parts illustrates as the part of user line unit DLU.
For remote underpopulatio area for the user provides service at an easy rate, having designed a kind of equipment is that fiber distribution concentrator OFDC is used for extending user line unit DLU, the square frame that marks of with dashed lines illustrates in the drawings.
It is light-guiding system OFL that this equipment has a line system, the discrete interface unit RT that this line system is preferably an optics loop line and inserts in this optics loop line, these interface units comprise some other user's link SLM in addition, and these parts will be designed to the part of user line unit under general geographical conditions.What this means that the expansion that realizes with equipment OFDC relates to is geographic sparsely populated area rather than the number of connection that is used to increase user line unit DLU.
Other part of equipment OFDC is a central interface unit COT, and this unit is used for the OFL of connection line system, and also is mounted to the part of user line unit simultaneously.
In addition, accompanying drawing shows people's computer PC one by one, this computer has constituted the man machine interface of expanding element OFDC, can carry out special operation and maintenance through this interface, cannot carry out from central operating terminal, because for system, the long-range of user's link that is driven through central interface unit COT is unknown.
The controller DLC of user line unit DLU has two processors, and wherein, processor DLUP is responsible for handling the task of extending, and as maintenance and information evaluation, and input-output-processor IOP is responsible for the passing on of dealing signal of user's connecting circuit SLM.After a kind of processor of mentioning be a kind of and the irrelevant unit of operating system scheme (APS) system because in this processor, prompting message is not carried out the logicality assessment.Therefore, can under the situation that does not change coding, be used for many kinds of APS schemes to it.
In addition, this input-output-processor IOP is responsible for the information exchange with central interface COT when carrying out method of the present invention, and central interface unit COT is connected as this machine user connecting circuit and distribution system.The information exchange of having mentioned above will further setting forth below.
If the subscriber terminal equipment that is connected with user line unit by an OFL of via line system and central interface unit COT proposes a requirement, central interface unit can connect remote subscriber terminal equipment in the face of the part that the controller IOP of user line unit DLU just shows as user line unit through this element so.
Therefore, controller IOP provides about all being provided with for central interface unit COT, the information of being regarded as operational at any time user's connecting circuit SLM in other words in exchange, wherein, initial at least do not have not provide the information of arranging about the current area of these circuit to system.Central interface circuit COT provides about which can be connected through central user's connecting circuit among these user's connecting circuits SLM to input-output processor IOP on this basis, and just which is the information of the part of user line unit DLU expansion.
According to these information, make the information of preparing to flow to discrete subscriber equipment always arrive central interface circuit COT by controller IOP, again from here message transport to these subscriber terminal equipments.Because central interface COT grasps all the information as spendable user's connecting circuit in this relation.Wherein suitably adjust, workability is achieved, also only handle user's connecting circuit that use is provided like this so can guarantee central interface COT through the executor of exchange.
The information that is prepared as the conveying of these long-range user's connecting circuit SLM and subscriber terminal equipment is with user's connecting circuit address of using as destination address, so that distribute accordingly in central interface COT.The information that arrives central interface COT in opposite transmission direction is mixed the address of relevant user's connecting circuit there and is used as original address.
Under the situation that lacks long-distance user's connecting circuit SLM, so change the information that indicates relevant long-distance user's connecting circuit by central interface unit COT in above-mentioned information exchanging process, promptly this user's connecting circuit shows as the part of user line unit DLU for the controller IOP of user line unit.If such user's connecting circuit SLM is controlled as the part of user line unit by controller IOP and on this can not connect, so just demonstrate lacking of user's connecting circuit on this basis.
Also can be implemented in information exchange between central interface unit COT and the controller IOP by other enforcement structure of the present invention, if to such an extent as to the information state that certain variation of connection state has controller IOP has been appearred in discrete interface unit realize always effective.
As above indicated, user line unit DLU also can contain many central interface unit COT.According to the first embodiment of the invention scheme, so these central interface unit are formed a group, only there is an interface to bear the interface function of exchange one side in this group, and also has only the controller IOP of this interface and user line unit DLU to carry out above-mentioned information exchange in view of the above.So the actual management for a certain definite long-distance user's connecting circuit is adjusted each other by central interface.
According to another scheme, all central interface COT not only in circuit one side also in exchange one side executive's interface function, in this case, they carry out above-mentioned information exchange with the controller IOP of user line unit DLU respectively at every turn.So controller IOP sets up a table for each central interface, in table, list the long-range user's connecting circuit that to connect through these interfaces and send the information of preparing to flow to long-range user line unit to this or that central interface COT by this.In this scheme, the special division of labor is carried out in the management of central interface unit COT is possible in order to manage long-range user's connecting circuit.This division of labor for example can be by the wiring decision of loading condiction line system under the dicyclo situation.
User line unit comprises some parts, and as detection part and warning device, these parts are generally a large number of users connecting circuit parts and concentrate setting, and can set up with these parts when needed and get in touch.The task of detection part (not illustrating in the drawings) is to detect the link performance of the connection line of subscriber connection line and branch equipment when needed.Because require to be electrically connected herein, thus under the situation that line system OFL is made up of the optowire system, must be in each discrete interface unit RT the such checkout equipment of discrete device.Not only long-range detecting unit but also the checkout equipment that is installed in addition in the user line unit can be with identical logical calls by location.If it is from the detection part among the long-range discrete interface unit RT that the detection task is arranged, this task is passed to controller IOP through central interface unit COT so, on this basis, send to relevant therewith required detection information relevant through central interface unit COT as above-mentioned the transmission the information at the detection part in interface unit RT to long-range subscriber terminal equipment.
When controlling the detection part of installing in the user line unit at the same time, these parts should not worked.Yet the inefficacy that the inoperation that occurs when this machine testing parts are controlled controller IOP is interpreted as controlling (all information that send the detection part of installing among the discrete interface unit RT to all pass through central interface unit COT transmit) in the case will be carried out clear data and exchange (this situation occurs in the control that does not have under the real data reception condition).
If this machine testing parts should be effectively really, so in a table that leaves controller IOP in, discrete interface unit RT is expressed as by corresponding registration through operational parts and does not exist, so that only control the detection part of user line unit DLU.
